Question

Resistance of $0.2M$ solution of an electrolyte is $50ohm$. The specific conductance of the solution is $1.4S{m}^{-1}$. The resistance of $0.5M$ solution of the same electrolyte is $280ohm$. The molar conductivity of $0.5M$ solution of the electrolyte in $S{m}^{2}mo{l}^{-1}$ is:

• A. $5\times {10}^3$
• B. $5\times {10}^2$
• C. $5\times {10}^{-4}$
• D. $5\times {10}^{-3}$

Answer 1

The correct option is C $5\times {10}^{-4}$
